June 12, 2021
Introduction
This is a brief workflow highlighting the exploratory analysis of survey data mined to assist in the writing of the manuscript, “Gender Disparities Persist in Endoscopy Suite” (Rabinowitz, et al.). Where appropriate, samples of the exact R syntax used will be displayed, along with the corresponding output (tabular data, graphical plots, maps, etc.).

QUICK CORRELATIONS & ASSOCIATIONS
A WARNING ABOUT THE FOLLOWING CORRELATIONAL DATA
The appropriate tack here would be to run a series of “point
biserial correlations,” which are correlations between a categorical
data (structured as T/F, 0/1, or ordinal, such as Low-Medium-High or
Freshman-Sophomore-Junior-Senior) against a continuous
variable. In our data, the only continuous variable is
GLOVE (glove size), so therefore, only the correlations where our
demographic categorical data is compared to GLOVE (e.g., BIRTHSEX,
AGEBAND, TRNG_LEVEL, HEIGHT_BAND) are statistically valid. For other
categorical variables that we have coerced into a binary numeric –
EVER_INJURED, TRANSIENT_PAIN_XXXX, ERGO_OPTIM – any correlations against
other categorical variables would technically be statistically
inappropriate to run, and should certainly never be reported. For our
purposes here, these “correlations” should be used only to guide us to
perform other, more appropriate statistical tests (such as logistic
regression, which is a natural extension of the Chi-Square analyses run
previously).

There apprears to be a few slightly significant “correlations” that might be worth exploring with simple logistic regression:
- First Year: Transient Pain with Sensitive Teacher & wth Ergo Optimization (based on borderline p-value, not displayed)
- Second Year: First Name & Ergo Optimization (???)
- Advanced: Transient Pain & Sensitive Teacher
Let’s explore further with few unadjusted/adjusted regressions where Transient Pain is the outcome and Ergo Optimization is the outcome:
- 1. Does Ergonomic Optimization influence reports of Transient Pain, with and without adjusting for Training Level?

## Tests are performed on the log odds ratio scaleConclusion: Sensitive Teacher is a highly significant effect before, and an extremely highly significant effect after adjusting for Training Level. Training Level itself is not a significant effect. (The model summary shows that there is significance among three levels of TRNG_LEVEL *when compared to the reference category, “Advanced.”) Beta for ST increases slightly from +0.9312 to +1.03915, meaning that as Teacher Sensitivity increases, reports of Ergonomic Optimization also rise. (The Odds Ratio in the adjusted model rose from 2.54 to 2.83, p= 0.0008. In other words, subjects who reported that their Endoscopy Suite environment was ergonomically optimized were 2.83 times more likely to have had instructors who were sensitive to their physical size/stature.)
When compared to the reference category (“Advanced”), ALL other training levels were significantly different (i.e., lower Beta weights). Does this suggest that teachers are more likely to be sensitive to ergonomics when dealing with older trainees, or does it suggest that younger trainees don’t really know what proper ergonomics should entail and, therefore, don’t know how to rate their instructors on this metric? (Does it take rising to the Advanced level before a trainee fully understands what constitutes “proper ergonomics?”)
4. First Name-No Permission does not appear to be correlated with Sex, but there does appear to be some correlation to Height Band. Is it significant?

Conclusion: When compared to the median Male height (HEIGHT=5, or 5’10-6’), the odds of the subjects’ first name being used without permission decreases as the reference height is approached. Subjects who were taller, however, had mixed results: Ones who were one band above the reference height (6’-6’4), had reduced odds of being disrespected in this manner; but the tallest subjects (HEIGHT=7, or > 6’4) had the worst odds ratio of all, 3.5, a group that is singularly comprised of males (n=2). Unfortunately, none of these results was statistically significant.
Even after adjusting for SEX, the significance of HEIGHT in the model did not improve (in fact, it worsened, likely because the variables HEIGHT and SEX are highly correlated). An unadjusetd model where SEX replaced HEIGHT as the predictor variable, yielded good results, but still not significant (p= 0.0938).
If the Height Category is collapsed into two groups – shorter than 5’7” and those who are 5’7” and above, there does appear to be some significance – even if controlled separately for Training Level and Race. Only controlling for Sex knocks this predictor out of sigificance, likely because the HEIGHT and SEX are so highly correlated.

PAIN_SCORE variable is created by turing six questions into numeric variables with binary values:
- Sustained endoscopy-related injury (Yes = 1, No/NA = 0)
- Transient pain experienced in hand (Yes = 1, No/NA = 0)
- Transient pain experience in neck/shoulders (Yes = 1, No/NA = 0)
- Transient pain experienced in back (Yes = 1, No/NA = 0)
- Transient pain experienced in legs (Yes = 1, No/NA = 0)

What happens if we focus on a subset of those questions, ones that are more specifically related to “equipment ergonomics/availability,” since something has to be driving the sex differences observed in the Pain/Injury score? For example:
- Equipment optimization (Yes=1, default=0)
